Abstract: At approximately 7:30 a.m. on Saturday, October 3, 1992, Employee #1 was dumping powdered magnesium into a mixer, working on a platform that measured approximately 16.5 square ft and was 10 ft high. A flash fire occurred when a static spark from the dust collector hose ignited a suspension of magnesium above the mixer opening. The magnesium suspension was created when the second drum was dumped. Employee #1 either jumped or fell to the concrete floor, gashing his head. He suffered third-degree burns over more than 90 percent of his body. He was taken to the Chicago Burn Center, where he died later that day.
